Detailed explanation-1: -The androecium is the male reproductive whorl of the flower which produces male gametes. The stamen is the androecium composed of anther and filament. The anther contains pollen sacs which produce pollen grains which are male gametophyte containing the male gametes.

Detailed explanation-2: -stamen, the male reproductive part of a flower. In all but a few extant angiosperms, the stamen consists of a long slender stalk, the filament, with a two-lobed anther at the tip. The anther consists of four saclike structures (microsporangia) that produce pollen for pollination.

Detailed explanation-3: -The stamen is the male reproductive organ. It consists of a pollen sac (anther) and a long supporting filament. This filament holds the anther in position, making the pollen available for dispersal by wind, insects, or birds.

Detailed explanation-4: -Pollen grains are the male sex cell of a plant. They are present in the anther of a flower.

Detailed explanation-5: -The male parts are called stamens and usually surround the pistil. The stamen is made up of two parts: the anther and filament. The anther produces pollen (male reproductive cells).
